Photovoltaic brackets, as the name implies, are racks for fixing photovoltaic modules. They are mainly responsible for protecting photovoltaic modules from damage by external factors such as strong winds. Therefore, sturdiness is their most important product attribute. But in fact, this seemingly simple bracket also has room for upgrading.
Light intensity directly determines the efficiency of the module. In order to maximize the power generation efficiency of the module, traditional fixed brackets generally choose an installation angle to better absorb sunlight, and this angle often chooses the angle with the strongest light intensity in a year. This angle cannot be adjusted, or can only be adjusted manually according to the seasonal changes in light, which is time-consuming and laborious.
Although traditional fixed brackets have chosen the seemingly best angle, in fact, the sun is changing in real time, and it is difficult for the module to fully absorb light. The best angle is only relative. Most of the time, the power generation efficiency of photovoltaic modules is compromised. So we started to launch solar tracking brackets to solve the problem of module absorption of light. The solar tracking bracket can track the movement of the sun in real time through angle adjustment, and always let the module face the best angle of sunlight, so as to improve power generation efficiency.
Different from the simple structure of fixed brackets, if the solar tracking bracket wants to realize the function of real-time tracking of sunlight, it must add a drive system and a control system. The control system is equivalent to the "brain" of the solar tracking bracket, which sends instructions to the drive system to control the real-time orientation of the bracket. After capturing the "command", the control system needs to adjust the direction and angle of the bracket. The tracking bracket makes the bracket no longer a decoration, but a key link to improve the efficiency of the component.
According to the difference in structure, solar tracking brackets can be divided into single-axis and double-axis. The single-axis can only rotate in one plane, and can be divided into a single flat axis and a single oblique axis according to the angle of the rotation axis, which can only make the inclination angle of the light as small as possible; the double-axis is controlled by two axes respectively. The direction and inclination of the component always allow the component to absorb the strongest light.
